The features of building on the basis programmable logic integrated circuits “arbiter” physical unclonable functions (APUF) are considered. problem asymmetry pairs APUF paths is indicated and negative impact this phenomenon their characteristics noted. A time measuring system based a ring oscillator scheme, which used to analyze paths, described. method for automatic balancing signal propagatio...

We present a comprehensive investigation into the complexity of a new private key storage apparatus: a novel silicon photonic physical unclonable function (PUF) based on ultrafast nonlinear optical interactions in a chaotic silicon microcavity that is both unclonable and impossible to emulate. This device provides remarkable improvements to total information content (raw cryptographic material)...

We introduce the notion of function composition, an interaction technique employed in several graphical user interfaces (GUIs), for use in physical chaining applications. Allowing the user to perform function composition in systems utilizing tangible user interfaces (TUIs) for input allows for more efficient use of the interactive workspace and the physical icons. In addition, it allows the use...

There is some evidence about the low relationship between physical prowess and cognitive function (Posthuma, Mulder, Boomsma & de Geus, 2002). The aim of this paper is to investigate the relationship between cognitive variables (spatial ability, reasoning, numerical ability, inductive reasoning, and reasoning and verbal comprehension) and physical prowess in sport performance (agility circuit, ...

Pediatric rheumatic diseases with predominant musculoskeletal involvement such as juvenile idiopathic arthritis (JIA) and juvenile dermatomyositis(JDM) can cause considerable physical functional impairment and significantly affect the children's quality of life (QOL). Physical function, QOL, health-related QOL (HRQOL) and health status are personal constructs used as outcomes to estimate the im...

BRILL, P. A., C. A. MACERA, D. R. DAVIS, S. N. BLAIR, and N. GORDON. Muscular strength and physical function. Med. Sci. Sports Exerc., Vol. 32, No. 2, pp. 412–416, 2000. Purpose: The purpose of this study was to evaluate the potential association of muscular strength and endurance at baseline with the prevalence of functional limitations at follow-up. Methods: Study participants were 3,069 men ...

The present study was carried out to investigate independent relationship between daily physical activity, microalbuminuria, and kidney function. The demographic characteristics and laboratory parameters were recorded for all patients. The determination of daily activities was carried out by Nottingham Extended Activities of Daily Living Scale (NEADLS) which was performed for each patient in an...

Digital circuit physical unclonable function (PUF) have been attracting attentions for the merits of resilience to the environmental and operational variations that analog PUFs suffer from. Existing state-ofthe-art digital circuit PUFs, however, are either hybrid of analog-digital circuits which are still under the shadow of vulnerability, or impractical for real-world applications. In this wor...

STUDY DESIGN A thematic review. OBJECTIVES To evaluate if physical activity enhances muscle strength, improves balance, and reduces the fall frequency and the fracture incidence. BACKGROUND One of the major medical problems of today is the increasing incidence of fragility fractures. Muscle strength and fall is one of the major determinants of a fracture. If physical activity could increase...

We present the first stateless construction of a cryptographically-secure Physical Unclonable Function. Our construct requires no non-volatile (permanent) storage, secure or otherwise, and its computational security can be clearly reduced to the hardness of Learning Parity with Noise (LPN) in the random oracle model. The construction is “stateless,” because there is no information stored betwee...
